Abstract
An electrolytic chlorine gas generating system is disclosed. The system includes an electrolytic cell generating the chlorine gas, a brine tank supplying saturated brine to the anode compartment of the cell, and an acid feed tank containing hydrochloric acid at sufficient concentration to maintain the anolyte brine at less than about pH 4.0. In operation, the brine tank contains solid sodium chloride which dissolves in the brine and replenishes the anolyte brine solution as chloride ion is consumed during electrolysis. The acid feed tank is in fluid communication with the brine tank so that the brine is maintained at a constant volume during electrolysis. A caustic system is also disclosed including a means for controlling caustic delivery.
